One quick tip for characters-do a character meal. You'll get to see many characters during your meal, without having to wait in line. Our favorite, food wise is Park Fare 1900. We haven't done it since they added Cinderella's stepsisters, but Cindy and Prince have always been great. Another good one is Breakfast at 'Ohanas with Lilo and Friends. Mickey, Pluto, Lilo, and Stitch. And again, good food.
We haven't done CRT (Cinderella's Royal Table) as I don't want to work that hard to get an ADR. Plus not all reviews of the food are favorable. And it takes 2 TS credits.
Another good one, for princesses, is Princess Storybook in Norway. Breakfast, lunch, or dinner.
Also good is Liberty Tree Tavern for dinner which features Minne, Goofy, Chip, and Dale.
If we do 1 or 2 character meals on our trip, then DD8 is usually satisfied with that. Then I usually have to make her get in line to get another one! Epcot has the Character Connection which only requires one line for several characters. In the World Showcase at Epcot you can find many characters. And usually they are tucked away, far from the people, and therefore less crowded.
Have a great time! (okay, it wasn't such a
quick tip!)
